fillColor property
The color that fills the checkbox, in all MaterialStates.
Resolves in the following states:
{@tool snippet}
This example resolves the fillColor based on the current MaterialState
of the Checkbox, providing a different Color
when it is
MaterialState.disabled.
Checkbox(
value: true,
onChanged: (_){},
fillColor: MaterialStateProperty.resolveWith<Color>((Set<MaterialState> states) {
if (states.contains(MaterialState.disabled)) {
return Colors.orange.withOpacity(.32);
}
return Colors.orange;
})
)
{@end-tool}
If null, then the value of activeColor is used in the selected
state. If that is also null, the value of CheckboxThemeData.fillColor
is used. If that is also null, then ThemeData.disabledColor is used in
the disabled state, ThemeData.toggleableActiveColor
is used in the
selected state, and ThemeData.unselectedWidgetColor is used in the
default state.
Implementation
final MaterialStateProperty<Color?>? fillColor;
